I'm running Kubuntu 15.04 on a fresh install inside VirtualBox on a Windows XP SP3 host.

This is simulated on a fresh Kubuntu install. In "Application Launcher Settings", I choose "Show applications by name". On the Favorites tab, I right click on one of the entries (for example, Firefox) and say "Sort Alphabetically (A-Z)".

However, the applications are not sorted by application name but rather their title. Since I am showing applications by name, I would expect sorting to honor that. The bug is that sorting should honor whatever I am showing the applications as (by name or purpose) but it only sorts by purpose.

For example, after sorting, I see this (parenthesis is for the smaller dark text underneath):

Dolphin
(File Manager)
IM Contacts
(Instant Messenger Contacts)
Kontact
(Personal Information Manager)
System Settings
(System Settings)
Konsole
(Terminal)
Firefox Web Browser
(Web Browser)


Reproducible: Always

Steps to Reproduce:
1. In Application Launcher, choose "Show applications by name".
2. In Application Launcher, in Favorites, right click on an entry and choose "Sort Alphabetically (A-Z)".
3. Observer that the sorting is not alphabetical by application name (despite it being prominent) but rather by application purpose (the darker text underneath).

Actual Results:  
The sorting is not alphabetical by application name (despite it being prominent) but rather by application purpose (the darker text underneath).

Expected Results:  
The sorting should be by whatever is chosen (either application name or purpose).
